incorrect Page/subpage displayed in info page

I have my bb-hosts splitted in 2 main category, one for network devices, and one for sistems. every category has the same set of subpages, like this:

/NET/INTERNAL/DATA-CENTER/hosta /SIS/INTERNAL/DATA-CENTER/hostb

now in the "hostb.info" page it displays:

Page/subpage: NET/INTERNAL/DATA-CENTER/

which is wrog. I tried to launch bbgen with the "--debug" option, but I have seen nothing useful :( my version is the last stable: Hobbit Monitor 4.1.1 any hints? thnks
